Google have announced the rollout of Android 4.1 Jelly Bean, which first arrives on Galaxy Nexus HSPA+ devices. If you haven't yet heard of the wonderful Jelly Bean OS, with its Project Butter and new features, you should definitely read up on it, especially if you're rocking a handset that is ready to receive the OS.

If you're rocking a Galaxy Nexus HSPA+ device, you should hopefully soon receive a prompt notifying you to update the handset over the coming days. Jelly Bean is set to hit other devices shortly, such as all Galaxy Nexus', Nexus S, Motorola Xoom and the Nexus 7, which will ship with Jelly Bean on-board later this month.

Some stand out features of Jelly Bean are Project Butter, where the engineers at Google have made Jelly Bean buttery smooth, the OS runs at a constant 60fps, which is just impressive. Something else to get excite over is Google Now, which can tell you today's weather before you start the day, how much traffic to expect before you leave for work, or your favorite sport team's score as they're playing.
